Pneumatic Pump is a new type of transport machinery, is the most novel type of pump in China.Using compressed air as the power source, all kinds of corrosive liquids, granular liquids, high viscosity, volatile, inflammable, highly toxic liquids can be exhausted by light absorption.Invented by American engineer William wilton, the pneumatic pump was introduced to China.There are five kinds of materials commonly used: plastic, aluminum alloy, cast iron, stainless steel and teflon.According to different liquid media, Diaphragm Pump adopts buqing rubber, chloroprene rubber, fluoro rubber, polytetrafluoroethylene, polytetrafluoroethylene respectively.The early domestic customers bought through the importer agent, the price is expensive and the maintenance is complicated.With the development of industry, the market share of domestic Pneumatic Diaphragm Pump has exceeded that of imported products.In order to install in a variety of special occasions, used to pump a conventional pump can not pump the medium, all achieved satisfactory results.
